Is there a way to sort the nouns learned by gender?

My native language has genders too, and I often confuse the German ones, I'm wondering if Duolingo has a function with which I could sort the nouns that I have learned in previous lessons based on their gender so I could memorize them better.

Hi, Alex,
I don´t think duolingo has such a funcion, I didn´t found anything like that. There are two things you can do.

Use www.leo.org and make a free account. Than you are able to save the words you want to memorize. You can also seperate them in two different files male/female.

Use http://codeisstyle.de make an free account and download it on your tablet/mobil. unfortunately this site is in german. But when you made it you can use it anywhere also without internet access. Type in the words (with the articel) you want to memorize and train them whenever you want.
